Engineering notes

How this family is specified

Compressed-air filtration is three separate duties, not one. The intake element protects the airend from atmospheric dust; the lube oil element keeps the oil clean; the air-oil separator keeps oil carry-over out of the discharge line. Each is specified differently, and each fails differently.

The family covers those three duties, plus precision and fine elements for downstream compressed-air treatment. Every model page states the part number, dimension, end-cap style and filtration rating we hold for it, so an element is matched against the one currently in the machine rather than against a catalogue picture.

Intake air element

Match outer diameter, height, end-cap and whether a secondary safety element is fitted. Paper, polyester and laminated media are all held.

Lube oil element

Spin-on and cartridge types. Match thread or cartridge geometry, bypass arrangement and micron rating; media is fiberglass or resin-impregnated paper.

Air-oil separator

Match bowl geometry, gasket and return-line arrangement. Separation performance is set by the media grade, not by the housing.

Precision / fine element

Downstream coalescing and fine filtration, with ratings stated per model down to 0.01 μm where the construction supports it.

Questions buyers ask about this family

How do I find the right element without a part number?

Send the compressor model and serial number, the element dimensions — outer diameter, height, inner diameter — and photographs of both end caps. We cross-reference to the platform and quote the closest match; if nothing in the catalogue matches, we cut to the drawing.

Are these original equipment parts?

No. They are aftermarket replacement elements cross-referenced to the platform. We are not affiliated with, endorsed by or authorised by the original equipment manufacturers; brand names are used only to describe compatibility.

Air filter and air-oil separator — what is the difference?

The air filter sits on the intake side and removes atmospheric dust before the airend. The separator sits after the airend in the oil circuit and removes oil mist from the compressed air. They are not interchangeable, even when they look similar.

Can you supply a full service kit?

Yes. Air filter, oil filter and separator are quoted as a set for one service interval and consolidated into a single shipment, which is the usual arrangement for annual maintenance contracts.

What lead time should I expect?

Common models ship from stock. Custom or low-volume items are quoted with a firm lead time once the drawing or sample is confirmed. State quantity and destination when asking.
